Claims.

One of the objects of this invention is to provide a window of improved construction which is equipped with novel means for securing it in a window opening, which securing means permits the window to be effectively sealed in position and also permits of its ready installation and removal.

Another more specific object of the invention is to provide a double glass window of the character described in which the outer sash is fixed and the inner sash is hinged or otherwise movably mounted on special inwardl extending flanges formed on the outer sash, which flanges constitute part of the above mentioned securing means.

Other objects and advantages of the inventionwill be apparent to those skilledin' the art upon a full understanding of the construction, arrangement and operation of the improved window. I

This application is a division of my earlier application, Serial No. 76,919, filed April 29; 1936.

Two forms of the invention are presented herein for the purpose of exemplification, but it will of course be appreciated that th invention is susceptible of embodiment in other structurally modified forms coming equally within the scope of the appended claims. 7 I

Fig. 9 is a sectional view which correspondsv to Fig. 5 but illustrates a modified. form of the 5 invention.

In the window structure which is illustrated in Figs. 1 to '7 inclusive the outer metal sheathing I'U of the car is provided with a rectangularopenmg H at the location of w, This open'-' 55? inner sash, in slightly spaced relation to thesidef taken on. the line ing is surrounded, on the inside of the car, with a metal frame [2 which is set back from the edge.

of the opening in order to leave a margin l3 of the sheathing exposed. The window includes a fixed outer sash I4 which'is positioned against the margin I3 of the sheathing and a movable inner sash [5 which is positioned against the inner face of the outer sash. The rails it of the outer sash are provided with L-shaped flanges l l composed of portions I8 which extend inwardly from the edges of the rails and portions l9 which project toward the frame 12 from the inner extremities of the portions 18'. The portions I8 form a frame 20 for the reception o the inner sash l5. The portions [9 lap flanges 2| on angle strips 22 secured to the frame [2, and are fastened to the flanges 2! by means or" screws 23.

The outer faces of the rails l6 of the outer sash are provided with dovetailed grooves 24 in which packing strips 25 of soft rubber or other suitable material are seated. When the screws 23 are drawn up, the packing strips 25 are compressed between the rails l6 and the margin i3 of the sheathing about the opening, whereby to produce a tightly'sealed' weatherproof joint between the outer'sash and the sheathing.

The inner sash 15' is fastened at its upper edge to the upper part of the frame 20' on the outer sash M by means of a hinge 26 which extends continuously the full width of the sash. This hinge permits the 'inner sash to be swung in wardly and upwardly awayfrom the outer sash when the opposed surfaces of both sash require cleaning.

The outer faces of the rails 21 of the inner sash are grooved, like the outer faces of the rails of the outer sash, and contain strips 28 of soft rubber or other suitable material which are compressed against the inner faces-of the railsof the outer sash when the innersash-is swung down into its closed position. The side and bottom rails of the inner sash are provided with flanges.

2g: whichslightly lap'the flanges I 9, and the side rails of the inner sash are provided at the bases of the. flanges 29 with narrow slots 30 in which closely fitting flanges 31 on looking strips 32 are shift'ably mounted. I

The locking strips 32which constitute the improved means for detachably lamping the inner sash against the outer sash on the interposed sealing strips 28are characterized by flanges 33 which are positioned flatl against the sides of the frame 20 on the outer sash. These flanges,

are secured to the edges of the side rails of the rails, by two or more screws 34 in the side rails which have conical heads 35 which fit between the beveled edges of vertically elongated slots 36 in the flanges 33. The screws 34 limit the extent to which the locking strips 32 can be shifted upwardly or downwardly with respect to the side rails of the inner sash, and they also adjustably limit the extent to which the locking strips can move away from the side rails. The locking strips 32 are forced away from the side rails of the inner sash as far as the heads 35 of the screws 34 will permit, by two or more leaf springs 31 which are secured to the flanges 33 of the lock ing strips by rivets 38 and bear resiliently against the side rails.

The flanges 33 of the locking strips are provided with two or more bayonet slots 39 which open toward the outer sash and coact with pins 40 which are mounted in the sides of the frame 20 on the outer sash and project toward the sides of the inner sash. The pins 40 are provided with enlarged button-like heads 4| which engage with the rear faces of the flanges 33 and prevent the latter from working away from the sides of the frame 20 after the locking connection has once been established. The slots 39 have inclined edges 42 near their entrances and have slightly indented edges 43 at their ends, with the result that when the inner sash is closed down with the entrances of the slots in the strips in register with the pins, and the angle strips shifted downwardly, the inclined edges 42 of the slots will cam against the pins and draw the inner sash into its fully closed position, after which the indented edges 43 will register with the pins and seat the same enough to yieldingly resist any movement of the strips in the opposite direction. In this way both sides of the inner sash will be drawn up uniformly into sealed association with the outer sash.

In fastening or unfastening the inner sash IS the locking strips 32 are shifted in either direction by a tool 44, on the order of the one shown in Fig. 8. The tool is inserted through a vertically elongated slot 45 in theflange 29 of the side rail 21, and through a relatively short slot 46 in the flange 3! of the locking strip to be moved, after which a notch 41 in the end of the tool is brought into engagement with a stud 48 on the frame 20. The stud 48 projects toward the inner sash through a notch 49 in the flange 33 of the locking strip. When the tool is now swung upwardly or downwardly, the stud 48 will act as a fulcrum for the tool and one of the side edges 50 of the same will engage with the opposed end of the slot 46 in the locking strip and cause the latter to shift up or down, depending on whether the tool is being swung upwardly to unfasten the inner sash or swung downwardly to fasten the same.

In the modification which is shown in Fig. 9 the locking strip is arranged with the flanges 52 thereof in lapped association with the inner face 53 of the inner sash rather than Within a groove provided in the edge of the inner sash as in the previously described embodiment. In all other respects the two constructions are substantially the same.

The locking strips have been described as apwith good results. Furthermore, the hinged connection of the inner sash with the outer sash might be omitted and the inner sash merely hooked into position or detachably connected in any other manner with the outer sash. The locking strips, although preferably carried by the inner sash, could obviously be applied over theedges of the inner sash as separately removable elements, without being actually fastened thereto.

While the improved window structure is particularly suited to air-conditioned railway cars, it will of course be appreciated that it can be used to advantage in any place where a double glass window is desired.
